Santorini

One of history’s most violent eruptions blew a hole in this round island 3,600 years ago. The sea flooded the crater — leaving the cliff-ringed bay, white-and-blue villages, and sunsets the world flies in to see.

About 3,600 years ago, one of the most violent eruptions in human history blew a huge gap in this round island. The sea flooded the crater, leaving the cliff-ringed bay we see today.

Along the clifftops, white-walled, blue-domed houses stack one above another like shells hung over the sea. At the northern tip, Oia is considered one of the most beautiful sunset spots in the world.

Three hundred metres below lies the deep-blue Aegean, where boats cross the caldera. The volcanic-ash soil grows the island’s own white wine — and some say the eruption inspired the legend of lost Atlantis.

Before you go

When is the best time to visit Santorini?+

May to early June and September: warm seas, working ferries, and fewer cruise crowds. July and August are hot, expensive, and shoulder-to-shoulder in Oia at sunset.

Where is the best place to watch the Santorini sunset?+

Oia is the famous one, but the viewpoints fill an hour or more ahead — arrive early or you will watch over heads. A caldera sunset cruise sidesteps the crush and gives you the cliffs from the water.

How many days do you need in Santorini?+

Two to three. One for Oia and Fira along the caldera rim, one for a boat trip to the volcano and hot springs, and time for a winery tasting on the island’s volcanic-ash soil.

Is Santorini overrated?+

The Instagram corners of Oia are genuinely crowded, and prices run high. But the caldera itself, the cliff villages, and the light at either end of the day are the real thing. Go in the shoulder season and stay away from the midday sunset scrum.
